Proof step 77 from proof junkrefs-put-null-01 (previous step)

is_reftype(fs .type), junkrefs(str, r0 ' + acc, ty, st[r -- fs ', refval(jvmref)]), ∀ str, ty, st, fs, r. ¬ junkrefs(str, acc, ty, st) ∧ is_reftype(fs .type) → ¬ junkrefs(str, acc, ty, st[r -- fs ', refval(jvmref)]) ⊦ junkrefs(str, r0 ' + acc, ty, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 76:
fs = mkfs(class, ty0, fieldvar), is_reftype(ty0), junkrefs(str, r0 ' + acc, ty, st[r -- fs ', refval(jvmref)]), ∀ str, ty, st, fs, r. ¬ junkrefs(str, acc, ty, st) ∧ is_reftype(fs .type) → ¬ junkrefs(str, acc, ty, st[r -- fs ', refval(jvmref)]) ⊦ junkrefs(str, r0 ' + acc, ty, st)
